   When using MPPE with MS-CHAPv2, the send- and recv-keys are mangled
   (see <a href="http://www.faqs.org/rfcs/rfc2548" class="link external">&raquo;&nbsp;RFC 2548</a>), however this function is
   useless, because I don&#039;t think that there is or will be a PPTP-MPPE
   implementation in PHP.
